TRAP FOR SANDER DEVICS.

Specification of Letters Patent. Patented Bleu'. 8, 1910.

Application led Apri124. 1909. Serial No. 491,945.

i0 alt whom it ymoz-y concern:

Be it Aknown that I, Hanny Vissnnlxc, a citizen. of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Traps for Sander Dey vices, of which the following is a speciication.

My invention relates to apparatus commonly known as locomotive sanders and especially to that type of such apparatus which is operable by fluid pressure inst aid of gravity, of which an example is illustrated in the Leach patent No. 433,686.

The principal objects of my invention are the provision of an improved form of construction of sand trap and fluid-pressure blast. connections therefor; the provision of a trap of an improved construction better adapted to resist the grinding action of the sand blast on the interior of the trap and thereby greatly increase its life as well as avoid the trouble and expense of constant repair and renewal thereof g the provision of an improved arrangement of passages and connections in the trap whereby sand therefrom is prevented from passing` into the pipingconneeted thereto and thus reducing the eciency. of the apparatus by clogging the piping and otherwise injuring it; and the provision of means whereby the trap may be readily cleaned, together with such additional benefits and advantages as will hereinafter appear.

. To attain the objects stated, vI have provided the'construction shown in the accompanying drawing which presents in cross section a trap embodying my preferred forni of construction.

From an inspection of this illustration `it will be observed that in carrying out my invention I provide the customary castbody portion, 10, adapted to be attacliedat some convenient place adjacent the sand box by means of bolts passing through the holes `11, 12 and 13.

The trap body, 10, is provided with suitable connections at 14, to receive the piping from the fluid pressure supply, at 15, to receive the sand pipe from the sand box, and at 1G to receive the sand delivery pipe leading toward the point of contact between the driver wheels and the rails.,

As is well known tothose skilled in the art to which this invention pertains, traps for sander devices of this class as heretofone constructed 'have needed constant attention, repair 'and replacement, and hence have proved ineiiicient in service and a source of expense, in the three following respects:

1st, the removable cap, 17, screw threaded to the body, 10, wears away rapidly owing I to the grinding action of the sand entering the trap from the connection, 15, and driven by the blast from the connection, 14, against the inner surface of said cap;

'2nd, the grinding away of the walls, 18, due to the same causes, which in my experience I have found to canse a whirling m0- tion of the sand which also grinds away the air nozzle, 15), enlarging the orifice thereof and destroying the contour of such orifice required for etiicientservice;

3rd, when the sander is at rest, sand from the connection, 15,' on account ofthe jar of the locomotive is gradually slinken into the pipe, Q0, and thence to the tank or compressor in sanders operated by compressed air, or into the boiler in Sanders operable by steam pressure, owing to the fact that the connection, 14, is on the same plane with or below the nozzle, 19.

To overcome the disadvantages just set forth it will be noted that- I have provided the interior of the cap, 1T, with an insert, 21, of comparatively soft material which. is not susceptible to the action of the sand blast, In practice I have found that lead is thc material best adapted to the purpose though rubber-of variousv compositions and other somewhatl yieldingly resistant materials may be used advantageously and are comprised within the spirit of my invention and intended to be covered by my claims.

I have likewise provided the passages, 18, and 2T with inserted linings, 22,v and 2S. of the same character and for the same reasons.

1V hile these inserts have been here shown,in the case of the insert, 21,as cast or pressed int'o the cap 17, with suitable dovetail connections in order to prevent displacement, and in the case of the insert, 22. as a piece of pipe or tubing cast or forced into position, it will be obvious that many other ways of securely fixing the inserts may be'designcd.

`It will also be observed that to prevent sand, coming from the passage, 15, from sifting through the nozzle, 19, into the pipe, c

removing *elle Soren' ping, the passage, which eonneins ssid well, 23, with tbe passage, 26, willi which the pipe, 20, has connection.

It Will be apparent that this `construetion not only allows sand to be readily removed from the elnnnber, 225, butalso, inasmuch as the eonneecion between tile pressure pipe, 20, and the. body, 10, is :Arbore ille sand pipe connection, i9, il; will be impossible for sand -to drift into the pressure pipe, 20, und thence into the parts connected therewith.

The operation of my improved (zrnp for sander devices vill be readily compreliended Without further explanation by suoli persons as are skilled in tlie nrt to Wliieb. my invention pertains.

Having lius described niy invention and illustrated use what I elziini new and desire to secure by Letters lslent is die following:
